A life-or-death struggle for a boy who fell through ice took a terrifying twist captured on video. An officer throws David Lewis, 17, a rope, when he plunges through the ice. His partner scrambles to rescue him. The boy, who had been in the frigid water for 20 minutes, can only watch the drama unfold. Just when you think it can’t get any worse, a second cop falls into the water, and a third cop has to come to the rescue. The boy is full of praise for the officers who put their lives on the line to save him.
